Return a tuple representing the internal state of the generator.

For more details, see set_state.

legacybool, optional

Flag indicating to return a legacy tuple state when the BitGenerator is MT19937, instead of a dict.

out{tuple(str, ndarray of 624 uints, int, int, float), dict}

The returned tuple has the following items:

  1. the string ‘MT19937’.

  2. a 1-D array of 624 unsigned integer keys.

  3. an integer pos.

  4. an integer has_gauss.

  5. a float cached_gaussian.

If legacy is False, or the BitGenerator is not MT19937, then state is returned as a dictionary.

set_state and get_state are not needed to work with any of the random distributions in NumPy. If the internal state is manually altered, the user should know exactly what he/she is doing.
